Typical Applications • Acids, alkalis • Sludge dewatering • Food ingredients • Brewing, winemaking • Chemical processing • Process mining • Dyes, inks • Flocculents • Cosmetics • Oil well dosing Capacity • 2 to 1,250 l/h 0.53 to 330 US ga l/h Pressure • Up to 72 bar 1,044 psi Temperature • Up to 120°C or 248°F (stainless steel models) Features and Benefits Gentle Pumping Action Minimize shear and crush damage to the pumped product. No pulsation or emulsification. Materials of Construction All pump components, except the body, coupling rod and suction chamber are supplied in stainless steel. The suction chamber is manufactured in high-density polyethylene. The end cover and mechanical seal housing is PVDF. For severe chemical environments, internal pump components are suppled in Hastelloy. Handles Gas Entrainment No air or gas locking in the pump. The positive seal formed by the interference fit between rotor and stator enables the pump to self prime, and it also allows tri-phase liquids i.e. solids, gases, and liquids to be easily handled. Sealed Joints Fully sealed drive train to maximize the life of the pump and minimize down time. Resilient Stator Flexible in operation and high resistance to wear. Available in a variety of materials allowing a wide range of products to be pumped. Robust Drives Specially selected drives and gearboxes for longer life. Options include fixed or variable speed drives with mechanical variable speed or frequency inverter. Interchangeable Components A number of Dosing Pump parts are interchangeable with the small Compact C Pump reducing stocked inventory. Flow Meter Available as an option for flow or temperature monitoring. industrial@nov.com nov.com/industrial
